Dashboard Filters

Interactive filter widgets (filter, filter-group) for a Platform Analytics Dashboard() (par_dashboard, short for Performance Analytics Report), and how they drive the other widgets on a dashboard. For the base Dashboard/DashboardWidget config schema and every other widget type, see the dashboard-guide topic -- this guide picks up where that one hands off filter-specific detail.

filter​

An interactive dashboard filter is wired via two parts:

  • datasource (singular, lowercase -- not the dataSources array charts use): where the filter's selectable options come from.
  • targets: an array of one or more places the selected value is applied. Each target is a datasource-shaped object. One filter can drive multiple widgets/tables by listing multiple targets.

Both datasource.payload and each targets[].payload follow the same three shapes depending on the field being filtered:

// Choice field (e.g. incident.priority) -- fieldType: 'choice'
componentProps: {
  filterName: 'Priority',
  filterComponentType: 'multiselect',   // or 'singleselect'
  datasource: { type: 'table', payload: { table: 'incident', field: 'priority', fieldType: 'choice' } },
  targets: [{ type: 'table', payload: { table: 'incident', field: 'priority', fieldType: 'choice' } }],
}
// Reference field (e.g. incident.assigned_to -> sys_user)
// datasource points at the REFERENCED table (its records are the options);
// the target points at the reference field on the fact table.
componentProps: {
  filterName: 'Assigned to',
  filterComponentType: 'multiselect',
  datasource: { type: 'table', payload: { table: 'sys_user' } },
  targets: [{ type: 'table', payload: { field: 'assigned_to', table: 'incident', primaryKey: 'sys_id' } }],
}
// Date field -- filterComponentType: 'date', with a default + allowed ranges
componentProps: {
  filterName: 'Created',
  filterComponentType: 'date',
  dateFilterView: 'reldates-only',       // or 'calendar-reldates'
  defaultSelectedDateRange: { range: 'SN_DYNAMIC_DATERANGE__THIS_WEEK', label: 'This week' },
  datasource: {},                         // date filters carry no options datasource
  targets: [{ type: 'table', payload: { field: 'sys_created_on', table: 'incident', primaryKey: 'sys_id' } }],
}
// Indicator-sourced (Platform Analytics breakdown) -- options come from a PA breakdown
componentProps: {
  filterName: 'Assistants',
  filterComponentType: 'multiselect',
  datasource: {
    type: 'indicator',
    payload: { targetTable: '<table>', factsTable: '<table>', field: 'sys_id', isChoiceType: false, breakdown: '<breakdown sys_id>' },
  },
  targets: [ /* same indicator payload, or a table target */ ],
}

Other supported keys: filterId (string; auto-generated if omitted), filterComponentType ('multiselect' | 'singleselect' | 'date'), filterElementType (e.g. 'pill'), filterElementLayout (e.g. 'vertical'), defaultSelectedItems (array), sort ('ASC'/'DESC'), isShowSelectedValueInPill (boolean), enableClearFilter (boolean), primaryActionLabel (e.g. 'Apply'), maxElements (number, default 500), cascadeScope (string -- links cascading filters), isDashboard: true.

filter-group​

A container that lays out multiple child filters together with shared Apply/Clear/Reset controls. The child filters live in groupConfiguration.filters[] -- putting targets at the top level alone renders an empty "No filters configured" group. Each entry in filters[] is a full filter config using the exact same datasource/targets/filterComponentType shapes as a standalone filter (above).

componentProps: {
  filterName: 'Incident filters',
  isDashboard: true,
  groupConfiguration: {
    filterId: 'group-incident-filters',
    showLabel: true,
    label: 'Incident filters',
    layout: 'horizontal',      // or 'vertical'
    spacing: 's',
    showSelectedValuesInPill: true,
    showBorder: true,
    showApply: true,
    showClear: true,
    showReset: false,
    showSeparator: true,
    filterMaxWidth: 300,
    filters: [
      {
        filterId: 'fg-priority',
        filterName: 'Priority',
        filterComponentType: 'multiselect',
        dateFilterView: 'calendar-reldates',
        defaultSelectedDateRange: { range: '' },
        defaultSelectedItems: [],
        filterConfigurations: [],
        datasource: { type: 'table', payload: { table: 'incident', field: 'priority', fieldType: 'choice' } },
        targets: [{ type: 'table', payload: { table: 'incident', field: 'priority', fieldType: 'choice' } }],
      },
      {
        filterId: 'fg-assigned-to',
        filterName: 'Assigned to',
        filterComponentType: 'multiselect',
        dateFilterView: 'calendar-reldates',
        defaultSelectedDateRange: { range: '' },
        defaultSelectedItems: [],
        filterConfigurations: [],
        datasource: { type: 'table', payload: { table: 'sys_user' } },
        targets: [{ type: 'table', payload: { field: 'assigned_to', table: 'incident', primaryKey: 'sys_id' } }],
      },
    ],
  },
}

groupConfiguration also supports showRoundCorners, bare, combineActions, and cascadeScope (for cascading child filters); each child filter additionally supports allowedDateRanges (array of {range, label}) when filterComponentType: 'date'.

How filters drive other widgets​

A filter or filter-group affects other widgets that (a) are in scope of the filter (see placement below), (b) draw from a table the filter targets, and (c) follow dashboard filters. Data widgets do the latter through followFilters: true and filterConfigurations: "@state.parFilters" (charts/list/single-score/dial/gauge/geomap and the indicator scorecard carry these by default after install; list-simple responds to matching filters too). Set followFilters: true explicitly on any widget you want to follow filters. The link is the target's table + field: a filter whose targets include { table: 'incident', field: 'priority' } filters every incident-sourced following widget in scope by priority. To drive multiple tables from one filter, add more entries to targets (each pointing at the relevant table/field). A filter with no in-scope widget matching its target renders and works but visibly changes nothing.

Placement decides scope. A filter placed in a tab's widgets[] drives only following widgets on that same tab. A filter placed in the dashboard's topLayout.widgets[] renders in the header, above the tab bar, and drives following widgets on every tab -- the conventional home for a dashboard's primary filters. Put shared filters in topLayout; keep a filter inside a tab only when it should scope that tab alone.

Dashboard({
  $id: Now.ID['my-dashboard'],
  name: 'My Dashboard',
  // Header filter (above the tabs) -- applies to following widgets on all tabs
  topLayout: {
    widgets: [
      {
        $id: Now.ID['hdr-filter'],
        component: 'filter',
        componentProps: {
          filterName: 'Priority',
          filterComponentType: 'multiselect',
          isDashboard: true,
          datasource: { type: 'table', payload: { table: 'incident', field: 'priority', fieldType: 'choice' } },
          targets: [{ type: 'table', payload: { table: 'incident', field: 'priority', fieldType: 'choice' } }],
        },
        width: 24, height: 6, position: { x: 0, y: 0 },
      },
    ],
  },
  tabs: [ /* widgets here set followFilters: true to follow the header filter */ ],
})

Avoidance​

  • Do not put a filter-group's child filters in a top-level targets array -- they belong in groupConfiguration.filters[], or the group renders "No filters configured".
  • Do not assume a filter/filter-group narrows a widget automatically -- the following widget also needs followFilters: true (and typically filterConfigurations: '@state.parFilters') and a targets table/field match, or the filter renders and works but visibly changes nothing.

Examples​

dashboard-widgets-with-filter​

A header filter driving two different widget types across a tab.
